SID & GUID in Active Directory

SID: Every object in the Active Directory is given SID. Like computer, user, group, printer, etc…so that Authentication can be easily performed.

GUID: GUID also is given to the objects in the active directory. When a new object is formed SID and GUID will be assigned but GUID will be unique in the AD.


For example, if a user is moved from the domain SID will change but GUID will not change.

GUID is unique in the entire forest SID is unique in the domain
GUID Does not change if the object moves from one domain to another. SID will change every time if an object moves from one location from another location.
GUID is published in the Global Catalog SID Will not publish anywhere
GUID makes it easier to locate an object in the entire forest. SID will locate within the Domain only
GUID also having the information and permission about users, groups, and Computers. SID has the information and Permissions of users, computers, and groups



Types of Group Accounts in Active Directory

There are two types of Groups in active directory.

1) Security

2) Distribution 

Security accounts are used for setting the permissions on the objects. Like, who can print data.

Distribution account is used for e-mail purpose only. It does not provide security.

Local Security Authority

LSA is a security subsystem. It is responsible for all the users’ authentication and authorization services on the local computer.

For example, a user logged on to the domain controller using his/her username and password,

If it is a valid user then, it means the authentication process is successful,

Then the LSA on the Computer creates a token.This token contains details like, “user is belonging to which group, and a SID for that user and SID for that Group and also includes the permissions assigned by Local security Policy (LSA) to the user and groups”. The entire LSA Process called “Token Evaluation”.
